Sargent LC-8271-24V Ll 26D Electrified Mortise Lock

Product Description

The SARGENT LC-8271-24V LL 26D is a fail-secure electrified mortise lock designed for controlled-access door applications in commercial and institutional buildings. Operating at 24 volts DC, this lock remains locked when power is lost, making it the correct choice for security-critical openings such as server rooms, stairwells, and restricted corridors. It features an L-style rose trim and L-style lever handle and ships less cylinder, meaning the installer supplies the key cylinder to match the facility's existing keying system. Licensed locksmiths, access control technicians, and commercial door hardware specialists are the typical trades performing this installation.

This mortise lock is suited for commercial interior and exterior doors where an access control system must integrate directly with the lock body. The fail-secure configuration ensures that electric strike release requires an active power signal, keeping the door locked during a power failure. The satin chrome finish designated 26D provides a brushed, low-glare appearance consistent with standard commercial hardware finishes. The less-cylinder design allows the facility to specify their own cylinder, whether small-format interchangeable core or conventional, without sourcing a separate trim package.

Installation Notes

Installation should be performed by a licensed locksmith or qualified access control technician familiar with commercial door hardware and low-voltage wiring practices. Disconnect all power to the access control panel and door hardware circuit before beginning installation or wiring. Verify that the door preparation, backset, and handing are correct before mounting the mortise lock body. Low-voltage wiring to the lock should comply with applicable NEC requirements for access control and security system circuits.
